SAFETY-PIN.

Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed February 15, 1915. Serial No. 8,135.

To all whom it may concern:

Be it known that I, HOWARD B. ROBINSON, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented a new and Improved Safety-Pin, of which thefollowing is a specification.

My invention relates to the devices above named, and an object of myinvention, among others, is to provide a device of this class in whichthe pin point shall be securely held against accidental displacement.

One form of pin embodying my invention, and in the construction and useof which the objects herein set out, as well as others, may be attained,is illustrated in the accompanying drawings, in which Figure 1 is a sideView of a pin embodying my invention.

Fig. 2 is a view in section through the same on plane denoted by dottedline 22 of Fig. 1.

In the accompanying drawings the numeral 6 indicates the rigid branch ofthe pin, 7 the limber branch and 8 the spring coil which are made in amanner well known to pins of this class, the rigid branch 6 beingsecured within the head or shield 9 in any suitable manner. This head orshield 9 has a plate 10, preferably comprising an integral part. of thehead, extending entirely across one side of the structure, and one edgeof the shield is folded to provide a socket 11 for the reception of thepoint 12 of the limber branch 7 of the pin.

A holding tongue 14: projects into the socket 11 and is normally held inposition to prevent the point 12 from disengagement from said socket,this tongue in fact constituting a bar that in its normal positionabsolutely prevents passage of the point 12 out of its socket.

This tongue 14 is formed as by means of slits extending from a pointnear the socket in which the rigid branch 6 of the pin is secured towardthe socket 11, and the portion between these slits is forced inwardlyand comprises the tongue. It has spring qualities suflicient to causeits free end to normally rest against the inner surface of the socket 11opposite the plate 10. The point 12 of the pin being pressed againstthis tongue 14, the latter will yield to permit the point of the pin topass into the socket 11 after which the tongue will immediately resumeits normal position against the inner wall of the socket after the pointof the pin has reached its seat, and the latter will thus be barred fromremoval from the socket, the distance between the end of the tongue 14:and the opposite wall of the socket 11 being suflicient to permit theend of the tongue to pass under the point of the pin. The tongue may bepressed inwardly to release the pin point and permit the latter to beremoved from the socket 11.

While I have illustrated and described herein a satisfactoryconstruction of device embodying my invention, this may be departed fromto a greater or lesser extent and yet be within the spirit and intent ofthe invention.

I claim- A safety pin including a head having a plate closing one sideof the head and with sockets formed in opposite edges of the head, arigid branch having its end secured in one of said sockets, a limberbranch insertible in the other of said sockets, and a resilient tongueformed by cutting slits crosswise of said plate to a point within theboundary of a lip of said socket for the limber branch, said tonguebeing pressed inwardly to resiliently engage the inner surface of saidlip whereby insertion of the pointed end of the limber branch ispermitted but accidental disengagement is prevented.
